The Envelope Editor is a simple, vector-based editor, where a sequence of connected control points defines an envelope. In most cases, you can use it to set up control signals and parameter automation by hand (e.g. to fade sections in or out, periodically shuffle between 2 audio signals, etc).
The Envelope Editor in AudioNodes supports an unlimited number of control points.
It’s used on the following Nodes:
Click or tap on empty area inside the envelope editor to place a control point.
In the case of the Envelope Node, the envelope can be edited on the Timeline. To enter edit mode, right click on the Envelope Clip, then choose Edit (for touch screens: tap the Envelope Clip, then tap on the edit button that appears over it).Envelope Node docs page
In the case of the Envelope Node, the envelope can be edited on the Timeline. To enter edit mode, right click on the Envelope Clip, then choose Edit (for touch screens: tap the Envelope Clip, then tap on the edit button that appears over it).
The vertical position of the control point denotes its value, which, in most cases, is what the envelope’s output value will be at a given time. Higher means a higher value. The horizontal position of the control point denotes its timestamp. This (again in most cases), marks when the control point will take effect. Further to the right means later.
When you create a control point, it’s automatically connected to its neighboring control points (if any), to form a continuous envelope.
You can simply drag control points around to move them. This will change their timestamp and value at the same time, depending on the drag direction.
Additionally, you can position control points with increased precision from their menu. Right click on a control point to open it, then choose Edit point (on touch: tap the point, then tap the triple-dot menu that appears above). This will open a dialog where the control point’s timestamp and value can be set by hand.
